Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy capping technology, specifically to a capping machine. Background Technology

[0002] Traditional capping machines are widely used in the packaging of bottled products such as food, beverages, and daily chemicals, primarily to automate the sealing of bottle caps and bottles. They can replace manual capping, significantly improving capping efficiency (3-5 times higher than manual operation) while reducing inconsistencies in sealing caused by manual operation. They meet the fundamental requirements for sealing reliability and production continuity in the mass production of various bottled products, making them one of the core auxiliary equipment in bottled product production lines.

[0003] In small- to medium-scale mass production of bottled products, traditional capping machines have significant limitations: uneven force transmission in some connecting frames leads to unbalanced force on the caps when the capping components are pressed, resulting in caps that are crooked, not sealed properly, or damaged. This not only affects product quality but also requires manual rework, reducing production efficiency. Utility Model Content

[0004] This utility model provides a capping machine to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A capping machine includes a base, a support frame fixedly connected to the top of the base, an extension frame fixedly connected to one side of the upper end of the support frame, a mounting plate fixedly connected to the surface of the extension frame, a cylinder fixedly connected to the top of the mounting plate, a connecting frame fixedly connected to the output end of the cylinder, a capping component fixedly connected to the bottom of the connecting frame, and a capping protrusion ring provided at the bottom of the capping component.

[0006] A further improvement of this utility model is that the connecting frame is a figure-eight frame structure, the bottom of the connecting frame is fixed to the top of the cover by welding, and the center of the connecting frame coincides with the center of the cylinder output end, so as to ensure that the cover force is evenly transmitted to the cover.

[0007] A further improvement of this utility model is that the capping ring and the capping component are integrally formed, the height of the capping ring is 5-10mm, and the inner wall of the capping ring is in clearance fit with the outer wall of the bottle cap to be capped, with a clearance ≤0.3mm, to ensure the limiting effect on the bottle cap during capping.

[0008] A further improvement of this utility model is that the support frame is a rectangular pipe pile structure with a wall thickness of 3-5mm, and the connection between the support frame and the base is provided with reinforcing ribs. The two ends of the reinforcing ribs are fixed to the side of the support frame and the top of the base, respectively, thereby enhancing the support strength of the support frame.

[0009] A further improvement of this utility model is that the extension frame is arranged perpendicularly to the support frame, and the length of the extension frame is 150-200mm.

[0010] A further improvement of this utility model is that: the surface of the extension frame is provided with a mounting groove that is compatible with the mounting plate, the mounting plate is embedded in the mounting groove and fixed by bolts to prevent the mounting plate from shifting.

[0011] A further improvement of this utility model is that the thickness of the mounting plate is 8-12mm, and the center of the mounting plate has a through hole adapted to the cylinder body.

[0012] A further improvement of this utility model is that the cylinder body passes through the through hole and is fixed to the top of the mounting plate to ensure the coaxiality of the cylinder installation.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: This utility model provides a capping machine. The connecting frame adopts an eight-shaped frame structure, with its center coinciding with the center of the cylinder output end. This ensures that the capping force output by the cylinder is evenly transmitted to all parts of the capping component, avoiding excessive or insufficient local pressure due to force imbalance, thus preventing cap misalignment at the source. The capping ring is integrally formed with the capping component, and the gap between its inner wall and the outer wall of the cap is ≤0.3mm. This further strengthens the cap's positioning function based on even force distribution, ensuring that the cap maintains the correct posture during the capping process and preventing misalignment that could lead to poor sealing. The support frame uses a rectangular pipe pile structure and reinforcing ribs to improve support stability, reduce vibration interference during equipment operation, and ensure the long-term stability of the coaxiality of the cylinder, connecting frame, and capping component. This avoids pressure transmission deviation caused by vibration, reduces labor rework costs, significantly improves production efficiency, and is suitable for the batch production needs of small and medium-sized bottled products.

[0016] The present invention will be further described in detail below with reference to embodiments: Example 1, as Figures 1-4 As shown, this utility model provides a capping machine, including a base 1, a support frame 2 fixedly connected to the top of the base 1, an extension frame 3 fixedly connected to one side of the upper end of the support frame 2, a mounting plate 4 fixedly connected to the surface of the extension frame 3, a cylinder 5 fixedly connected to the top of the mounting plate 4, a connecting frame 6 fixedly connected to the output end of the cylinder 5, a capping component 7 fixedly connected to the bottom of the connecting frame 6, and a capping protrusion ring 8 provided at the bottom of the capping component 7.

[0017] In this embodiment, before the equipment is started, the support frame 2 adopts a rectangular pipe pile structure with a wall thickness of 3-5mm, and the connection with the base 1 is reinforced with ribs, which can effectively disperse the vibration stress during equipment operation and avoid support deformation caused by long-term use. The extension frame 3 is vertically fixed to the support frame 2, and the mounting plate 4 embedded in the mounting groove on its surface is locked with bolts. The central through hole of the mounting plate is precisely matched with the cylinder body of the cylinder 5, ensuring that the cylinder is coaxial with the capping structure below after installation, laying the foundation for uniform force transmission in the future. The bottled product with the cap already on is placed under the capping component 7, and the position of the bottle is adjusted so that the cap is directly below the capping ring 8. The capping ring 8 and the capping component 7 are integrally formed, and the gap between its inner wall and the outer wall of the bottle cap is ≤0.3mm. At this time, the bottle cap can be initially embedded in the inner side of the ring, forming a pre-limiting position to avoid the bottle cap shifting laterally during subsequent pressing and to ensure accurate pressing reference.

[0018] Example 2, as Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the connecting frame 6 is an eight-shaped frame structure, the bottom of the connecting frame 6 is fixed to the top of the capping component 7 by welding, and the center of the connecting frame 6 coincides with the center of the output end of the cylinder 5, ensuring that the capping force is evenly transmitted to the capping component 7. The capping protrusion ring 8 and the capping component 7 are integrally formed structures, the height of the capping protrusion ring 8 is 5-10mm, and the inner wall of the capping protrusion ring 8 is in clearance fit with the outer wall of the bottle cap to be capped, with a clearance ≤0.3mm, ensuring the limiting effect on the bottle cap during capping. The support frame 2 is a rectangular pipe pile structure, the wall thickness of the support frame 2 is 3-5mm, and the connection part between the support frame 2 and the base 1 is provided with reinforcing ribs. The two ends of the reinforcing ribs are fixed to the side of the support frame 2 and the top of the base 1, respectively, to enhance the support strength of the support frame 2.

[0019] In this embodiment, after the device is started, the cylinder 5 receives the operating signal, and its output end extends downward along the coaxial direction of the through hole in the mounting plate 4, pushing the connecting frame 6 to move downward synchronously. Since the connecting frame 6 has an eight-shaped frame structure and its center is completely coincident with the center of the cylinder output end, the pressing force output by the cylinder can be evenly distributed through the two force arms of the eight-shaped frame and transmitted to the entire top plane of the pressing part 7, avoiding the problem of "local force concentration" of traditional connecting frames and ensuring that the pressing part is subjected to balanced force.

[0020] Example 3, as Figures 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the extension frame 3 is arranged perpendicularly to the support frame 2. The length of the extension frame 3 is 150-200mm. The surface of the extension frame 3 is provided with a mounting groove that matches the mounting plate 4. The mounting plate 4 is embedded in the mounting groove and fixed with bolts to prevent the mounting plate 4 from shifting. The thickness of the mounting plate 4 is 8-12mm. The center of the mounting plate 4 is provided with a through hole that matches the cylinder body of the cylinder 5. After the cylinder body of the cylinder 5 passes through the through hole, it is fixed to the top of the mounting plate 4 to ensure the coaxiality of the cylinder 5 installation.

[0021] In this embodiment, driven by uniform force, the capping component 7 moves the capping ring 8 at the bottom downwards synchronously. The inner side of the capping ring always fits against the outer wall of the bottle cap, and the bottle cap's posture is restricted by a fit gap of ≤0.3mm to prevent it from tilting under pressure. As the capping component continues to move downwards, uniform pressure is applied to the bottle cap, making the bottle cap and bottle body tightly pressed and sealed. During this process, the stable support of the support frame 2 and the coaxial positioning of the mounting plate 4 further avoid pressure deviation caused by equipment vibration, ensuring that the force transmission path is consistent for each pressing and preventing bottle cap damage or poor sealing. After pressing is completed, the output end of the cylinder 5 returns to the upward reset, driving the connecting frame 6, capping component 7 and capping ring 8 back to their initial positions. The operator takes out the bottled product with the caps completed, puts in the material to be capped again, and repeats the above process to realize continuous pressing operations for small and medium-scale batch production.

[0022] The working principle of this capping machine will be explained in detail below.

[0023] like Figures 1-4As shown, before the equipment starts, the support frame 2 adopts a rectangular pipe pile structure with a wall thickness of 3-5mm, and the connection with the base 1 is reinforced with ribs, which can effectively disperse the vibration stress during equipment operation and avoid support deformation caused by long-term use. The extension frame 3 is vertically fixed to the support frame 2, and the mounting plate 4 embedded in the mounting groove on its surface is locked with bolts. The central through hole of the mounting plate is precisely matched with the cylinder body of the cylinder 5, ensuring that the cylinder is coaxial with the capping structure below after installation, laying the foundation for uniform force transmission in the future. The bottled product with the cap already on is placed under the capping component 7, and the position of the bottle is adjusted so that the cap is directly below the capping ring 8. The capping ring 8 and the capping component 7 are integrally formed, and the gap between its inner wall and the outer wall of the bottle cap is ≤0.3mm. At this time, the bottle cap can be initially embedded in the inner side of the ring, forming a pre-limiting position to prevent the bottle cap from shifting laterally during subsequent pressing, ensuring accurate pressing reference. After the equipment is started, the cylinder 5 receives the running signal, and its output end extends downward along the coaxial direction of the through hole of the mounting plate 4, pushing the connecting frame 6 to move down synchronously. Because the connecting frame 6 has an eight-shaped frame structure, and its center is completely aligned with the center of the cylinder output end, the capping force output by the cylinder can be evenly distributed through the two force arms of the eight-shaped frame and transmitted to the entire top plane of the capping component 7. This avoids the problem of "local force concentration" in traditional connecting frames and ensures that the capping component is subjected to balanced force. Driven by the uniform force, the capping component 7 moves the capping ring 8 at the bottom downwards synchronously. The inner side of the capping ring always fits against the outer wall of the bottle cap, and the bottle cap's posture is restricted by a fit gap of ≤0.3mm to prevent it from tilting under pressure. As the capping component continues to move downwards, uniform pressure is applied to the bottle cap, making the bottle cap and bottle body tightly press and seal. During this process, the stable support of the support frame 2 and the coaxial positioning of the mounting plate 4 further avoid pressure deviation caused by equipment vibration, ensuring that the force transmission path is consistent for each press and preventing bottle cap damage or incomplete sealing. After the pressing is completed, the output end of cylinder 5 returns to the upward reset, driving the connecting frame 6, the capping part 7 and the capping ring 8 back to the initial position; the operator takes out the bottled product with the caps completed, puts in the material to be capped again, and repeats the above process to realize the continuous pressing operation for small and medium-sized batch production.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
